5. セットアップ

1. バッテリーの取り付け: Open the battery compartment cover on the back of the meter. Insert the required batteries, observing correct polarity. Securely close the cover.
2. テストリード接続: 巻の場合tage, resistance, continuity, and frequency measurements, insert the red test lead into the VΩHz input jack and the black test lead into the COM input jack.
3. 電源オン: Rotate the rotary switch from the 'OFF' position to the desired measurement function.

6. 操作手順

6.1. AC/DC 電流測定

Rotate the dial to the AC A or DC A position. Open the clamp jaws by pressing the trigger. Enclose a single conductor within the jaws. Ensure the jaws are fully closed. The current reading will be displayed. For DC current, observe the polarity indicated on the display.

6.2. AC / DC Voltag測定

ダイヤルをV~（AC Vol）に回しますtage) または V- (DC Voltage) position. Connect the test leads to the circuit points where voltage is to be measured. The voltag読み取り値が表示されます。

6.3. 抵抗と導通の測定

Rotate the dial to the Ω (Resistance) or Continuity position. For resistance, connect the test leads across the component. For continuity, touch the probes to the points to be tested; an audible tone indicates continuity.

6.4.非接触Voltage (NCV) 検出

Rotate the dial to the NCV position. Bring the top of the clamp meter near a live conductor. The NCV sensing antenna will detect the presence of AC voltage, indicated by an audible beep and/or visual alert.

6.5. その他の機能

• 最大/最小： Press the MAX/MIN button to record the maximum and minimum readings.
• REL（相対）: Press the REL button to set the current reading as a reference and display subsequent measurements as a deviation from this reference.
• 零： Used to zero out the display for DC current measurements to compensate for residual magnetism.
• ホールド： HOLD ボタンを押して、ディスプレイ上の現在の読み取り値を固定します。
• Backlight/LED Light: Activate the display backlight or the built-in LED flashlight for improved visibility in low-light conditions.

7. メンテナンス

• クリーニング： 広告でメーターを拭くamp 布と中性洗剤。 研磨剤や溶剤は使用しないでください。
• バッテリー交換: Replace batteries when the low battery indicator appears on the display. Use only the specified battery type.
• ストレージ： 長期間使用しない場合は、液漏れを防ぐため電池を取り外し、涼しく乾燥した場所に保管してください。

8。 トラブルシューティング

• 表示されない/読み取りが不安定: Check battery condition and replace if necessary. Ensure test leads are properly connected. Verify the function switch is in the correct position.
• 現在の読み取り値が正しくありません: Ensure only one conductor is within the clamp jaws. Use the ZERO function for DC current if needed.
• 導通ビープ音なし: Check if the circuit is de-energized. Ensure probes make good contact.
